发明名称 ASSEMBLY FOR MANUFACTURING HOLLOW MACHINE PARTS BY DIFFUSION BONDING AND SUPERPLASTIC FORMING, ITS USE AND PROCESS FOR MANUFACTURING SUCH MACHINE PARTS
摘要 PROBLEM TO BE SOLVED: To provide an assembly for enabling the full extraction of a gas residue generated by the decomposition of a diffusion stop-off product. SOLUTION: An assembly (10') is provided with a stack of at least two basic parts (12') and a sealed reservoir (14) with an open edge, and the basic parts are joined each other at their fringes except portions forming a passage so that a hollow is defined between them. The basic parts have at least one surface which faces the hollow and is covered, with a pattern, with thermally decomposable binders containing the diffusion stop-off product and the edge of the reservoir is joined to the passage in the stack by sealing so that an internal space of the reservoir is connected with the hollow, and the reservoir is kept under a partial vacuum, having a capacity adequate to absorb gases generated as a result of the decomposition of the binder when the stack is at a thermal decomposition temperature for the binder.
